Title: Artificial shellac and process of making the same
IPC: C08G63/06
Filed: 1927-10-06
Abstract: 309,384. Marks, E. C. R., (Alox Chemical Corporation). Oct. 6, 1927. Drawings to Specification. Sizing and weighting. - Hydroxy-carboxylic acids insoluble in petroleum and in water, and resembling shellac are obtained together with formic acid, light and heavy ketones and aldehydes, and water-insoluble carboxylic acids soluble in petroleum by oxidizing with air or gases containing free oxygen petroleum hydrocarbons at 130- 160‹ C. and 150-300 lbs. pressure until 20-40 per cent of petroleum-insoluble acid is produced, the latter being then separated and treated to remove readily volatilizable compounds. Distillates from Pennsylvania oil of 40-36‹ BÚ., or other fractions such as those of 33-18‹ BÚ. may be used as initial material. The oxidation is effected in presence of a catalyst such as a manganese, copper or iron compound (manganese oleate being mentioned) or an unsaponifiable product from the oxidation. The hydroxy-acids insoluble in petroleum are washed with water, and subjected to vacuum-distillation at 10-20 mm. pressure preferably with admission of air or steam, the temperature being 140-275‹ C. The residue in the still resembles shellac and is an acid or anhydride forming soaps with alkalies. It is insoluble in fatty and mineral oils and soluble in carbon tetrachloride. It varies (according to the extent of the distillation) from a hard brittle solid to a tacky material, the latter alone being soluble in alcohol and in benzene. It is of high dieletric capacity, paper impregnated with an alcoholic solution giving a greater dielectric capacity than one impregnated with a shellac solution of the same strength. It is adapted for use for all insulation purposes for which shellac is used. The brittle product may be used in the form of its calcium salt, which is readily ground. The product may also be added to paper pulp to give a hard paper of high dielectric character. Instead of treating by distillation, the hydroxy-acids may be con. verted into the shellac-like product by exposure in thin films to a current of air. Specification 309,382, [Class 2 (iii), Dyes &c.], is referred to.

Abstract: 843,657. Door-operating appliances. PETERS & CO. Ltd., G. D. Aug. 20, 1958 [Aug. 23, 1957], No. 26643/57. Class 65(1) A lever 1, for the remote manual operation of one or more doors, e.g. passenger vehicle doors, through motion transmitting means, comprises a manually-releasable spring loaded catch member 14 mounted on the lever and provided with an inclined abutment surface 17 which engages a fixed pin 20 to retain the lever in a pre-selected position (corresponding to the closed position of the doors), and which can ride over the pin, against the spring loading of the catch, to release the lever upon the application of a pre-determined force to the doors. The motion transmitting means may be a mechanical linkage or a hydraulic master and slave system. The lever 1 is a tube pivotally mounted at 5 between a pair of fixed plates 2, and a rod 8, axially movable in the tube, connects the latch member 14 to a spring loaded press-knob 11 by which the lever is normally released. The latch member slides axially in slots 15 in the lever, and has a second, vertical, abutment surface 16 which makes normal engagement with a second fixed pin 20 in the open position of the doors. The doors are thus positively locked in the open position, but can be forced from the closed position in an emergency. The pins 20 act as distance pieces between the plates 2, and are located in one of a plurality of pairs of apertures 24 in the plates to allow for variation in the range of movement of the lever. Each pin has an eccentric central portion 21 for engagement with the latch, and a fine adjustment of the range of movement of the lever can be obtained by rotating the pin on its axis.

Title: Method of consolidating granular mineral masses
IPC: C09K17/04
Filed: 1934-09-17
Abstract: Granular mineral masses are consolidated by supplying separately to the voids therein water containing lime, and carbon dioxide, calcium carbonate being thereby precipitated in the masses.  When waterlogged masses are treated, the surface may be covered with an impervious layer-e.g. a concrete foundation raft, or puddled clay-the two constituents being then pumped into the masses under the raft &c. The concrete raft may have been treated with lime-water and carbon dioxide as described in the parent Specification.  Finely - divided material such as flue-dust may be added to the lime-water as a suspension to assist in filling the voids.

Title: Improvements in or relating to polymer irradiation
IPC: C08J9/10
Filed: 1959-08-06
Abstract: Graft polymers are prepared by a process wherein a polymer, other than a natural or synthetic rubber, and a polymerizable monomer are immersed in a liquid, preferably water, which is a non-solvent for both the polymer and the monomer and then exposed to an ionizing radiation such as gamma rays or X-rays.  The polymer may be cellulose, which may be in the form of a low-density wood agglomerate, cellulose acetate or a polyamide, and the monomer may be vinyl acetate, styrene or n-butyl acrylate. In a preferred process the polymer is swollen by treatment with monomer before immersion in the non-solvent liquid.  When the polymer is in divided form the reaction mixture may be caused to flow in conduit means past a source of radiation. Specifications 831,197 and 831,833 are referred to.

Title: Improvements in or relating to a process for producing mono-alkylbenzenes
IPC: C07C2/68
Filed: 1947-10-08
Abstract: Mono-alkyl benzenes are produced by contacting gaseous olefins with benzene in the presence of an aluminium chloride-aromatic hydrocarbon complex, separating the complex from the alkylated liquor, and drying and purifying the benzene and the poly-alkyl benzene fraction of the product by contact with said complex.  The treated poly-alkyl benzene gives an increased yield of mono-alky benzene in the subsequent dealkylation with benzene.  Ethylene, after contact with the alkylation product in a stripping column, is fed to an alkylator at 80-150 DEG  C., containing benzene, mono- and poly-alkyl benzenes, and catalyst complex which are kept circulating.  Fresh aluminium chloride and, if desired, HCl or ethyl halide, are also added.  The alkylate, after separation of complex and stripping, is fractionated to separate benzene, ethyl benzene, and poly-ethyl benzene.  Complex, after use in the dealkylation, is mixed with benzene and poly-ethyl benzene which, after the purification, pass to the dealkylator. Other olefins gaseous under the reaction conditions, such as propylene, butylene or amylene, may be used similarly.  Specification 590,492 is referred to.
